          returns the largest of them.  
          b) Write a program which makes use of function to display all such numbers which 
          are divisible by 7 but are not a multiple of 5, between 1000 and 2000.  
       VII. Exercise programs on recursion & parameter passing techniques.

       VIII. Exercise programs on Tuples.  
          a) Write a program which accepts a sequence of comma-separated numbers from 
          console and generate a list and a tuple which contains every number. Suppose the 
          following input is supplied to the program: 34, 67, 55, 33, 12, 98. Then, the output 
          should be: ['34', '67', '55', '33', '12', '98'] ('34',67', '55', '33', '12', '98').  
          b) With a given tuple (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), write a program to print the first half 
          values in one line and the last half values in one line.
